摘要

针对制药过程中产生的高浓度的含磷废水，研究了一种新的处理方法：采用复合钙盐法回收其中的磷。研究了钙盐的投药量，pH，复合钙盐中氯化钙和石灰的摩尔比对该制药废水中磷的去除效果的影响，并对磷渣的产量、有效磷（以P2O5计）含量以及磷渣中 N

N-二甲基甲酰胺（DMF）的含量进行测定。结果表明，在最佳条件下此法可将废水中的磷浓度从31000 mg·L-1降至0.5 mg·L-1以下，渣中有效磷含量在18%左右，达到磷肥优级品标准，并且通过GC-MS和光度法未检测到有害物质DMF。

Abstract

A new method of recovery of phosphorus from high concentration phosphorous-containing pharmaceutical industry wastewater with composite calcium was proposed. It was found that the efficiency of phosphorous removal from the wastewater was affected by dosage of composite calcium

pH of solution

and the mole ratio of calcium chloride and calcium oxide in the composite calcium. The production of phosphorus residue

the available phosphorus (calculated as P2O5) and N

N-dimethylformaide (DMF) in the phosphorus residue were also determined. The content of phosphorus in the wastewater could be reduced from 31000 mg·L-1 to less than 0.5 mg·L-1

and the content of the available phosphorus in the phosphorous residue was about 18%

approaching the national standard for superior grade product of phosphorus fertilizer. Furthermore

the poisonous material DMF was not detectable in the residue by GC-MS and spectra photometry.
